Stuck in endless boot loop. Please help. - Nexus 6 Q&A, Help & Troubleshooting

Hello,
I was using my Nexus 6 normally when it froze up so I just rebooted it. When I rebooted it, it entered an endless loop which I can't resolve. I can power/volume down to get to the bootloader screen, but when I try to boot into recovery, I get the TWRP screen but it ask for me to enter my passcode and my screen isn't active so I can't. I don't know what to do. Any help would be appreciated. Thanks.

First, from bootloader, use the following fastboot commands:
fastboot format cache
fastboot format userdata

For the password, just enter it normally on the TWRP keyboard.

thanks for the reply!
It just says waiting for device when I try the fastboot commands.
Also, the keyboard isn't active at all when I get to the TWRP keyboard. And if the screen sleeps, I get a "swipe to unlock for TWRP and can't do that either due to the screen not active.

Hmm It's not listed in device manager.

What OS is on your PC? The problem is that your PC is not "seeing" the device in fastboot.

If on Windows 8.1, you have to disable driver signature checking.

Place file on your desktop. Hold shift and right click on desktop. Select open command prompt here.

Maybe a stupid question. Did you plug the phone into the same port you always use? My computer only recognizes my phone on one port. Then try fastboot commands.
I'm sure i can get it to recognize on the other ports but didn't feel like troubleshooting that far.

Give it a reboot if you're getting not recognised as a command message.

Start by reinstalling the drivers.
---------- Post added at 12:35 PM ---------- Previous post was at 12:28 PM ----------
The reason you cant get to recovery is because the method you used (the only method) to root this phone overwrites the recovery partition in order to gain read/write access to the system partition. In order for you to get things going again you need to fastboot the system, and recovery partitions. If that doesn't work, you will have to flash completely back to stock.
i installed all the drivers once again and it stils not working, i am at the same. in de ADB console it recognizes the phone but only by the way that i said. i cant get in fastboot because when i type in the console ADB reboot bootloader it reboots into the fastboot but them it doesnt recognize the phone
there is no more ways for flash a new room? or something like that?

You are using the wrong command. adb doesnt work in fastboot mode. Once you are in bootloader mode you need to use fastboot commands. Type:

You need to unzip it. Once unziped, move the recovery.img and system.img to the folder on you computer that contains fastboot.exe.
---------- Post added at 01:34 PM ---------- Previous post was at 01:29 PM ----------
Once you are have done that you need to boot your phone back into fastboot mode. When you are in fastboot mode you need to type the following commands:
Code:
fastboot flash recovery recovery.img
Code:
fastboot rlash system system.img

Right on. Glad you got it working again. If you are on a model that is not Verizon or ATT you can unlock your bootloader and flash a real recovery like TWRP or CWM.

Does fastboot detect your device? If so, copy a recovery to the folder where your fastboot executable is. Open a command prompt in that folder. Boot device to fastboot mode. In command window type "fastboot boot recovery.img", without the quotes and where 'recovery.img' is the file name of the recovery you want to use.
This will boot your device to the specified recovery without needing button combos.

Oh you mean for adb connectivity? You can put the phone into bootloader mode for a fastboot connection
yoh cant connect to adb while in the bootloader, only fastboot.

if you are in a bootloop, and can not boot up to enable oem unlock in the dev options, then you have essentially a bricked device, nothing can be done. if oem unlocking is enabled, you can unlock your bootloader and flash a factory image.

however, you are on 5.0.1. you can still unlock your bootloader with fastboot and then flash the factory image for m.

Hummm, i never met this before... maybe the HONOR-MultiTool could help you, you have to open MultiTool(first of all, download it) and press Extras, then Bootloaderz then relock my bootloader(make sure your phone is ON, connected with HiSuite and USB Debugging), then choose "i have a code", and finally you have to type your code(ONLY CODE!!) then enter, and make sure your phone reboots into fastboot and asking you to "lock bootloader?" choose yes. If anything goes wrong, let me know, i will answer ASAP.
